The Windows version of the Crisis Trojan is able to sneak onto VMware implementations, making it possibly the first malware to target such virtual machines. It also has found a way to spread to Windows Mobile devices.
"Many threats will terminate themselves when they find a virtual machine monitoring application, such as VMware, to avoid being analyzed, so this may be the next leap forward for malware authors," wrote Takashi Katsuki of Symantec in a blog post
Samples of Crisis, also called Morcut, were first discovered about a month ago targeting Mac machines running various versions of OS X. The Trojan spies on users by intercepting e-mail and instant messenger exchanges and eavesdropping on webcam conversations. Launching as a Java archive (JAR) file made to look like an Adobe Flash Installer, Crisis scans an infected machine and drops an OS-specific executable to open a backdoor and monitor activity.
